The unique lattice work design of the Percstone environmental unit allows for sand, pea gravel or turf fillers, each of which creates its own distinctive look. These pavers work well in driveways, parking courts and other areas where drainage is a problem. Percstone is an erosion control unit that provides visual definition for the paved space. For tough spots that really require solid pavement but are unable to support it, Percstone is the answer.
